CLOSURE FOR RECEPTACLES.

Specification of 'Letters Patent.

Patented Nov. 7, 1916.

Application filed March 2, 1916. Serial N o. 81,698.

To all whom t may concern Be it known thatI, JOHN WAGNER, a citizen of the United States, residing at Long Island City, in the county of Queens and State of New York, have invented certain new and useful Improvements in Closures for Receptacles, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved closure for receptacles and has for itsprimary object to provide a cover or closure which is so constructed that in its application, it will frictio-nally co-act with the container wall to tightly retain the cover in its closed position over the open end of the container.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure l is a vertical sectional view through a sieve or other receptacle having my improved cover or closure applied thereto. Fig. 2 is a view in top plan of the device as herein disclosed with the cover or closure member removed; and Fig. 3 is a fragmentary sectional view of the cover member.

As herein illustrated, C denotes a container of predetermined dimensions and configuration and having its upper end open and provided at diametrically opposed points with the lifting and operating members l. The container C is preferably cylindrical in form and is provided with interior spaced supporting lugs 2. An annular member 3 fits snugly in the upper portion of the container and rests upon the lugs 2, said annular member having an inwardly projecting liange 6 on its lower edge to support the screening fabric 5 vof' a sieve or separator indicated at S. A ring or annulus 4 is secured within the annular' member 3 and upon said sieve. It is to beY understood that this sieve mounting and construction constitutes no part of the present invention but is simply illustrated for the purpose of disclosing one type of container to which my improved closure is applicable, as the invention is of particular advantage when used upon containers or vessels to be vibrated for the purpose of agitating the contents thereof.`

A denotes a cover or closure member for the open end of the container C and as herein disclosed, said cover or closure member A comprises a body portion 7 adapted to overlie the open end of the container C and provided at its marginal portion with the depending flange 8 adapted to overlie the periphery of the container C and frictlonally engaged therewith, whereby the cover or closure member A in applied posltion, effectively serves to prevent the escape of dust or the like during the separation operation.

As herein embodied, the upper marginal portion of the flange 8 is provided with the outstanding annular lip 9 which is opera tively engaged by the returned part 10 of the marginal portion of the body 7, whereby the flange 8 is effectively 7. The fla-nge 8 has its lower marginal portion pressed outwardly to afford an annular bead ll substantially V-shape in cross section and the lower edge of the bead ll is arranged slightly inward of the upper portion of the flange 8, whereby the lower marginal portion of the bead 1l on account of the inherent resiliency possessed thereby, will contact with the periphery of the container C under tension whereby the cover or closure member A is effectively held against displacement during the separating operation and whereby the escape of dust from within the container C is prevented.

From the the foregoing description, itis thought to be obvious that a device constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim:

The combination with a container, of a closure therefor having a body wall and an annular wall Xed to the outer edge of said body wall and normally inclined inwardly toward the center thereof, the major portion of said annular wall having frictional bearsecured to the body 'f ing engagement upon the outer face of the lower edge of said annular wall upon the l0 container wall, the iree edge of the annular wall of the container.

wall being formed with annular portions In testimony whereof I hereunto aliX my obtusely. inclined with respect to ea-cli other signature in the presence of two witnesses. and projecting outwardly in converging re- JOHN WAGNER lation, said annular inclined portions being spaced from the container Wall when the Vtnesses: y K closure is applied and resiliently acting to J. G. MULVANEY, cause an inward bearingV pressure of the JOHN STANG.
